WARNING

The 5500A Calibrator can producevoltages up to 1000 V rms and must beprogrammed with caution to preventhazardous voltages from beingproduced without sufficient warning tothe operator.

Programs should be written carefullyand tested extensively to ensure safeoperation of the 5500A Calibrator.Fluke suggests that you include errorcatching routines in your programs.These error catching routines willassist in detecting programming errorsthat could result in the instrumentbehaving differently to your intention.By setting the Service Request Enable(SRQ) register, described in paragraph5-60, the 5500A Calibrator can beprogrammed to cause an SRQ when anerror is detected. The followingprogram example shows a skeletonprogram including error catching:

10 PRINT @4, “*CLS” ! Clear status20 PRINT @4, “*SRE 8” ! Set SRE Error Avail.30 ON SRQ GOTO 1000 ! Enable SRQ Function

100 ! Body of program here

900 STOP ! End of program

1000 REM Start of SRQ Handler ! Start routine1010 PRINT @4, “FAULT?” ! Request fault code1020 INPUT @4, A% ! Input fault code1030 PRINT @4, “EXPLAIN? ”;A%! Request fault text1040 INPUT @4, A$ ! Input fault text1050 PRINT “Fault ”;A$“ detected” ! Print message1060 PRINT @4, “STBY” ! Place 5500A in standby1070 STOP

COMMAND SYNTAX (cont)

General Rules

1. Separate parameters with commas.

2. Numeric parameters up to 15 significant digitsand exponents in the range +/-1.0E+/-20.

3. Null parameters cause an error, e.g., theadjacent commas in OUT 1V, ,2A.

4. Expressions, for example 4+2*13, are notallowed as parameters.

5. Binary Block Data can be in one of two IEEE488.2 formats:

Indefinite Length Format Accepts data bytesafter #0 until the ASCII Line Feed character isreceived with an EOI signal (for RS-232, a linefeed or carriage return will terminate the block).

Definite Length Format The non-zero digitspecifies the number of characters that willfollow in the <digits> field.

Extra Space or Tab Characters

One space after a command is required. You caninsert extra spaces or tabs as desired.

Terminators

Terminator Characters

Function ASCII Control C Code

# Code

CarriageReturn

13 Chr(13) <Cntl> M \n

Line Feed 10 Chr(10) <Cntl> J \r

Backspace 8 Chr(8) <Cntl> H \b

Form Feed 12 Chr(12) <Cntl> L \f

6

COMMAND SYNTAX (cont)

IEEE-488 Interface The 5500A sends the ASCIIcharacter Line Feed with the EOI control line heldhigh as the terminator for response messages.

RS-232 Interface The 5500A Calibrator returnsan EOL (End of Line) character with eachresponse, selectable as CR, LF or both CRLF.

Incoming Character Processing

1. The most significant data bit (DIO8) is ignored.

2. All data is taken as 7-bit ASCII.

3. Lower-or upper-case characters.

4. ASCII characters less than 32 (Space) arediscarded, except for characters 10 (LF) and 13(CR) and in the *PUD command argument.

Response Message Syntax

Response Data Types

DATA TYPE DESCRIPTION

Integer Decimal numbers to 32768.

Floating Numbers plus an exponent.

String ASCII characters withindouble quotes (“string”).

Binary Block Data Defined by the IEEE-488.2.

0 RQSMSS

ESB MAV EAV ISCB 0 0

RQS Requesting Service. Set to 1 whenever bitsESB, MAV, EAV, or ISCB change from 0 to1 and are enabled (1) in the SRE. WhenRQS is 1, asserts the SRQ control line.

MSS Master Summary Status. Set to 1 wheneverbits ESB, MAV, EAV, or ISCB are 1 andenabled (1) in the SRE. This bit can be readusing the *STB? command in serial remote.

ESB Event Status. Set to 1 when one or moreenabled ESR bits are 1.

MAV Message Available. The MAV bit is set to 1whenever data is available in the 5500A’sIEEE-488 interface output buffer.

EAV Error Available. An error has occurred andan error is available to be read from theerror queue by using the ERR? query.

ISCB One or more enabled ISCR bits are 1.

For RS-232, transmitting the ^P character (holddown the <Cntl> key and press P) returns theSPLSTR (Serial Poll String) and the status byte.

Service Request (SRQ) Line

IEEE-488 Bus control line that asserts to notifythe controller that it requires some type of service.

RS-232 Sends the SRQSTR string over the serialinterface when the SRQ line is set.

Service Request Enable Register (SRE)

The SRE enables or masks the bits of the SerialPoll Status Byte. The SRE is cleared at power up.

11

Output Queue

The output queue is loaded whenever a query isprocessed, and holds up to 800 characters. If thequeue is empty, the 5500A Calibrator does notrespond to the INPUT statement. The MessageAvailable (MAV) bit in the Serial Poll Status Byte is1 if there is something in the output queue and 0 ifthe output queue is empty.

Error Queue

When a command error, execution error, ordevice-dependent error occurs, its error code isplaced in the error queue where it can be read bythe ERR? command. The error queue contains upto 16 entries.
